Engineered with durable metal construction, this regulator ensures reliable performance for models including the Saturn SC1, SL, SL1, and SW1.

• Durable metal material for long-lasting use
• Non-adjustable design for precise factory-set pressure
• Push-in inlet type with a 0.51 inch (13.0 mm) diameter
• Hose outlet type with 0.35 inch (9.0 mm) diameter
• Single inlet and outlet ports for straightforward installation
• Bolt mounting type for secure attachment
• System pressure rating of 43 psi

Technical Details and Specifications

The FP10725 fuel injection pressure regulator by Delphi is constructed entirely of metal, providing strength and resistance to wear in demanding engine environments. It features a push-in inlet port measuring 0.51 inches (13.0 mm) in diameter and a hose outlet port of 0.35 inches (9.0 mm), designed to fit the fuel lines of Saturn SC1, SL, SL1, and SW1 models. The regulator is non-adjustable, maintaining a consistent system pressure of 43 psi to ensure optimal fuel delivery and engine performance. Installation is facilitated by a bolt mounting type, allowing for a secure and stable fit within the fuel injection system.

Compatible Vehicles and Applications

This Delphi fuel injection pressure regulator is compatible with the following Saturn models:

• Saturn SC1
• Saturn SL
• Saturn SL1
• Saturn SW1

It is specifically designed to regulate fuel pressure in these vehicles’ fuel injection systems, helping to maintain engine efficiency and performance.

Common Issues Addressed by the FP10725 Regulator

• Fuel pressure fluctuations causing engine hesitation or stalling
• Poor fuel economy due to inconsistent fuel delivery
• Hard starting or rough idling conditions
• Fuel leaks or pressure loss in the fuel injection system
• Check engine light triggered by fuel system faults

Installation Notes and Tips

When installing the Delphi FP10725 fuel injection pressure regulator, ensure the vehicle is cool and the fuel system is depressurized to avoid fuel spray. The bolt mounting type requires proper torque to secure the regulator without damaging the mounting points. Verify that the push-in inlet and hose outlet connections are properly seated and free of debris to prevent leaks. Replacement should be performed by a qualified technician familiar with Saturn fuel injection systems.
